You need to hire a lawyer in Maryland and challenge the entries in your name for these other convictions. What it sounds like is, someone has a license in your name, or has a similar name which has been confused with you and now you two have the same driving record. Either way, until you clear this up, that other person is going to continue to drive, violate the law, and screw up your driving record. Do not ignore it, because insurance companies and other states will see this record and make decisions affecting you based on those entries.
Can the MVA case worker just say that I have to take this 26 week course? The obvious answer is yes, since it happened right? The real question is what can you do about it. Now that is a tough question to answer, especially because you are trying to get this done from California. You need to contact a Maryland lawyer whom can gather more information from you and work toward a resolution. It probably won't be easy so you better get started.
